Ed Bangs wrote “MFWP [Montana, Fish, Wildlife and Parks] veterinarian Mark Atkinson examined and keyed out some ‘unidentified eggs’ submitted by Kent Laudon (MFWP Kalispell, MT), from wolf NW112M. They were in fact, proglottids of Echinococcus granulosus, the tapeworm that is responsible for Hydatid disease. The tapeworm has a two stage life cycle. The adult tapeworm is attached in the canid gut and sheds eggs that are ingested by ungulates. The eggs develop into embryos that migrate out of the gut to form cysts in the ungulate’s lungs, liver, and other tissues. When the tissue with cysts is ingested by canids, the larval tapeworm develops into an adult tapeworm in the canid digestive tract- starting the life cycle again. Human infection from wild canid scat is almost nonexistent in North America, but anyone routinely handling wolf scat should be careful not to inhale eggs from dried wolf scat and to careful wash after handing wolf scat to avoid ingestion of eggs.”
People who hate wolves have tried to scare people with facts like these, but the truth is the scat of every predatory mammal and omnivores (like bears) is likely to carry parasites. This includes free running dogs and cats.
People do not normally smell or eat dog, coyote, cougar or bear scat. The scat of the domestic cat has infected millions of folks with toxoplasmosis, which is primarily dangerous to pregnant women and those with compromised immune systems
So if you are dumb enough to eat wolf shit, you certainly do have something to worry about, but that disgusting thought should put this “threat” into perspective.
For information about a much more likely threat, read “Intestinal Parasites of Dogs and Cats.
